How to copy banner-anchor of spirit theme (sprite.png)

Dear Team,
I'm back again. Exploring Spirit.
No matter how I try, I can't fix this... I want to copy the banner-anchor icon (see screenprint). I have found the sprite-svg/png - that's no problem, but I don't know what ELEMENT I should use to get it doen. An image? (But how to set the css), TEXT element (same problem). I checked and looked but I am probably too dumb for this. But then again: I think when you have a template like this and you show people nice things, then I think it also should be clear how to achieve these things. In other words: more information.
But as I said: maybe I overlook a simple thing.
Please advise,
Kind regards,
Josh Haijer
